Microblogs autocomplete tagging doesn't work if a user inputs more than the first name

Description

Here are the steps to reproduce (SO must be running using Oracle 11 or Sybase 15):

1. Go to Dashboard
2. Go to Microblogs
3. Type in the following into the status update text field: This is Social #Office. Click Post
4. Click on the word "Office"
5. A tab with the word "Office" will appear, but the user will only see a message saying "You do not have any microblog entries" instead of the newly created post
